Experimental Operation of the Schober Abrasion Tester

Author:QINSUN Released in:2023-08 Click:107

The Schober abrasion tester adopts the rotational wear test method, which is used to test the wear resistance of automotive interior materials, especially leather interior linings. Qisnun Precision Electromechanical Technology Co., Ltd. is a manufacturer and welcome any inquiry from customers.

Applicable standards:

DIN 53863part2 \"Abrasion test of textile surfaces (Rotational wear test)\", GME Standard60345, GMW Standard3283, VW/Audi PV3908

Main settings:

01. Rotation speed: 75L/min;

02. The cone angle is 166°;

03. The tilt angle of the test head holder is 7°;

04. Sample size: 100 cm2;

05. Test area: 50 cm2;

06. Sample arch height is adjustable, with measuring accessories, range 0-10mm;

07. Sample pressure: 0.5N to 25N adjustable;

08. A set ofload weight: 50g, 100g, 250g, 500g, 1000g, 1500g.

Principle of the test:

The circular sample is installed on the rotating test head, and the sample is carried using rotary friction with the friction object (sandpaper) clockwise and counterclockwise at a certain speed, pressure and number of rotations. The rubbing object maintains linear contact with the sample, producing a tangential friction effect. Change the direction of rotation every 100 times of friction (can be adjusted) and evaluate the test results by mass loss and hole generation.

Experimental operation:

1. Use the instrument configuration accessories to install the sample after temperature and humidity treatment on the sample holder to form a rotary test head;

2. Utilize the arch height test device to adjust the protruding height of the test head according to relevant standards or other requirements, usually 5-8mm;

3. Install the test head with the sample on the instrument On the test head mounting plate on the platform, the test head is installed and fixed through the cooperation of the locating pin on the mounting plate and the locating hole under the test head;

4. Use the pressure plate on the instrument. The friction device of the object installs the friction sandpaper on the bottom surface of the pressure pressure plate, and the locking device ensures that the sandpaper is tight and installed flat;

5. Manually pull the pressure plate lifting lock on the right side of the pressure plate outward, lower the pressure plate so that the sandpaper is contact with the specimen surface on the test head;

6. Install the corresponding weights on the weight shaft above the pressure plate (configured with 1500, 1000, 500, 250, 100, 50g each calibrator weight) to make it rub against the sampleAdd some pressure. Select the required pressure value based on the sample weight per unit area.
